Abstract (en)
An intake system for an engine allows supercharging using the dynamic effect of intake air has a surge tank (4Q,4L) for a cylinder group in which cylinders are ignited in a sequence discontinuous with each other, a second surge tank (4b,4R) for another cylinder group in which cylinders are ignited in a sequence discontinuous with each other, a first upstream intake passage (5g,5L) for supplying intake air to the first surge tank, a second upstream intake passage (5g,5R) for supplying intake air to the second surge tank, a connecting tank (9) for communicating intermediate portions of the individual intake passages (6a- with each other, and a short connecting passage (31) for communicating upstream portions of the first upstream intake passage and the second upstream intake passage with the connecting tank (9). When the number of engine revolution is high, intake air is supplied to each of the cylinders through the connecting tank and the individual intake passage by taking advantage of the short connecting passage and bypassing a long upstream intake passage and the surge tank. Further, the short connecting passage does not adversely affect the effect to be produced by resonant supercharging because the upstream portion of the intake passage is communicated with the connecting tank. The intake system can shorten the length of passage for supplying intake air when the number of engine revolution is high due to inertia supercharging, without sacrificing the effect to be achieved by resonant supercharging. <IMAGE>
